Nokia, the world's biggest mobile phone maker, issued on Monday a global recall for 14 million faulty chargers made by a subcontractor this year.

The recall concerned "approximately 14 million (chargers) globally," Nokia spokesperson James Etheridge told AFP.

Nokia said the chargers could cause an electrical shock and would be replaced without any extra cost.

The Finnish firm said in a statement it was "not aware of any incidents or injuries related to these chargers."

Etheridge said the recall did not concern China, Britain, Brazil, Argentina and some other countries.

Nokia said the potentially dangerous charges were models AC-3E and AC-3U, manufactured between June 15, 2009 and August 9, 2009; and the AC-4U model, manufactured between April 13, 2009 and October 25, 2009.

The AC-3E charger was marketed in Europe while the two others were sold to the North and Latin American markets.

All three models were manufactured by subcontractor BYD.

Nokia said customers could check if their charger was potentially hazardous on the company's website.
